Not to be confused with Luigi's final smash.
The Negative Zone Machine is a corrupted Mr. Coffee that Ruigi made with Kinopio-Kun whilst playing Pokemon Laggray. Apparently the link cable got too hot and both connections disconnected simultaneously. Some people say "it's just the Value Invert filter on GIMP" but they're just haters. You use it to activate the Negative Zone.
After the Negative Zone Machine was created, both Ruigi and Kinopio-Kun wanted it and got a trial as quickly as they could. WaNess decided that it was an imported coffee machine and that Japanese people couldn't have it. And in 2007 Luigi got it, but he didn't like the negative zone it gave him. Ruigi bought if off Luigi for ¥1000.
